摘要
目的探讨消化性溃疡(peptic ulcer,PU)患者动态心电图(electrocardiogram,ECG)心率变异性的临床意义及系统化护理干预在动态ECG中应用的效果.方法采用方便取样的方法 ,选取2016-07/2017-07在天津医科大学第二医院行健康体检的患者128例,其中PU患者64例作为试验组,另选64例体检健康的患者作为对照组,对照组采用常规动态ECG护理,试验组采用系统化护理干预,对所有体检的患者行24 h动态ECG检测,将各组心率变异率的时域指标与频率指标进行统计学分析,并分析两组患者ECG伪差发生率及患者满意度.结果试验组SDNN、SDANN、低频功率(low frequency,LF)得分均低于对照组(124.5 ms±8.3 ms vs 130.3 ms±7.2 ms、109.2 ms±7.4 ms vs 128.4 ms±8.9 ms、122.4 ms/Hz±9.5 ms/Hz vs 136.3 ms/Hz±10.6 ms/Hz),差异无显著性(P>0.05).试验组反映副交感神经张力改变的r M S S D、P N N50、高频功率(h i g h frequency,HF)得分均高于对照组(45.8 ms±8.7 ms v s 25.8 m s±12.3 m s、13.5±4.9 v s 10.9±4.3、93.5 ms/Hz±8.3 ms/Hz vs 71.3 ms/Hz±9.5 ms/Hz),L F/H F为0.7±1.4 v s 1.6±3.1,差异有统计学意义(P<0.05).试验组E C G明显伪差为5例,发生率为7.8%,伪差发生率明显低于对照组,试验组非常满意患者44例,不满意患者0例,护理满意度明显高于对照组患者(90.6%vs 60.9%),差异有统计学意义(P<0.05).结论给予患者系统化的护理干预能够降低ECG伪差发生率,同时提高患者护理满意度,保证动态ECG监测的准确性与有效性,值得在临床应用.
AIM To explore the clinical significance of dynamic electrocardiogram（ECG） heart rate variability in patients with peptic ulcer（PU） and the effect of systematic nursing intervention on dynamic ECG.METHODS One hundred and twenty-eight subjects were enrolled at the Second Hospital of Tianjin Medical University from July 2016 to July 2017, including 64 patients with PU（experimental group） and 64 healthy volunteers（control group）. The control group was given conventional nursing, and the experimental group was given systematic nursing intervention. All subjects underwent dynamic ECG monitoring. The time domain index and frequency index of heart rate variability were statistically analyzed. The incidence of ECG artefacts and patient satisfaction were also analyzed.RESULTS The standard deviation of NN intervals, standard deviation of average NN intervals, and low frequency（LF） were lower in the experimental group than in the control group（124.5 ms ± 8.3 ms vs 130.3 ms ± 7.2 ms, 109.2 ms ± 7.4 ms vs 128.4 ms ± 8.9 ms, 122.4 ms/Hz ± 9.5 ms/Hz vs 136.3 ms ± 10.6 ms）, but the differences were not significant（P〈0.05）. The root mean square of successive differences, the proportion derived by dividing NN50 by the total number of NN intervals, high frequency（HF）, and LF/HF, which refl ect changes in parasympathetic tone, differed significantly between the experimental group and the control group（45.8 ms ± 8.7 ms vs 25.8 ms ± 12.3 ms, 13.5 ± 4.9 vs 10.9 ± 4.3, 93.5 ms/Hz ± 8.3 ms/Hz vs 71.3 ms/Hz ± 9.5 ms/Hz, 0.7 ± 1.4 vs 1.6 ± 3.1, P〈0.05）. The incidence of ECG artefacts was significantly lower in the experimental group than in the control group（P〈0.05）, while the rate of satisfaction to nursing was significantly higher in the experimental group（90.6% vs 60.9%, P〈0.05）.CONCLUSION Systematic care intervention can reduce the incidence of ECG artefacts, improve patient satisfaction, andensure the accuracy and effectiveness of dynamic ECG monitoring.
